How Starch Transfer Works in Corrugating
From Glue Kitchen to Application and Recirculation
The starch transfer process begins in the glue kitchen, where adhesive is prepared and sent through a closed-loop system across the corrugator.
In corrugated cardboard manufacturing, starch glue transfer and circulation are critical to ensuring consistent adhesive performance, strong bonding, and efficient production.
Because this industry operates under continuous 24/7 conditions, optimizing starch transfer systems is essential to:
- Reduce energy consumption
- Improve adhesive consistency
- Minimize downtime and maintenance
- Ensure high-quality board production
Key Process Steps:
1. Starch Glue Transfer
- Starch adhesive is prepared and stored in a buffer tank
- Pumps transfer glue to:
- Singlefacer
- Glue machines
- Local storage near application points
2. Continuous Starch Circulation
- Glue is continuously circulated between:
- Buffer tank → glue pans → return loop
- Prevents settling, viscosity variation, and film formation
3. Starch Recovery and Reuse
- Excess glue is collected under the machine
- A eturn pump, also called return pump, transfers it back to storage
- Adhesive is recirculated and reused
This full loop is essential for maintaining consistent starch quality and minimizing waste
